Wrist protector

Abstract

A wrist protector includes a contact pad to be worn on a wrist of a user, a plurality of air tubes disposed on the contact pad, a pump configured to inject air from an outside into the plurality of air tubes, and a discharge valve configured to discharge the air stored in the plurality of air tubes to the outside.

What is claimed is: 
     
       1. A wrist protector, comprising:
 a contact pad to be worn on a wrist of a user; 
 a plurality of air tubes disposed on the contact pad, the plurality of air tubes comprising a main air tube and a sub-air tube; 
 a pump configured to inject air from an outside into the plurality of air tubes; 
 a discharge valve configured to discharge the air stored in the plurality of air tubes to the outside; 
 a main plate configured to support a lower portion of the main air tube; and 
 a loop plate and a sub-plate respectively formed at left and right edge portions of the contact pad, 
 wherein the sub-air tube comprises: 
 a first sub-air tube disposed between the main plate and the loop plate; and 
 a second sub-air tube disposed between the main plate and the sub-plate. 
 
     
     
       2. The wrist protector of  claim 1 , further comprising:
 a fixing hole provided in the contact pad and configured to enclose at least one finger of the user. 
 
     
     
       3. The wrist protector of  claim 2 , wherein
 the main air tube configured to support a lower portion of the wrist of the user, and 
 the sub-air tube configured to communicate with the main air tube, 
 wherein an angle formed by the main air tube and the sub-air tube is adjustable. 
 
     
     
       4. The wrist protector of  claim 3 , wherein the pump, the discharge valve and the fixing hole are disposed on the same side relative to the main air tube. 
     
     
       5. The wrist protector of  claim 3 , wherein the main air tube includes an air-noninjectable region formed at a central portion of the main air tube in a longitudinal direction of the main air tube. 
     
     
       6. The wrist protector of  claim 1 , further comprising:
 a check valve configured to allow an airflow from the pump to the plurality of air tubes and block an airflow from the air tubes to the pump. 
 
     
     
       7. A wrist protector comprising,
 a contact pad to be worn on a wrist of a user; 
 a plurality of air tubes disposed on the contact pad; 
 a pump configured to inject air from an outside into the plurality of air tubes; 
 a discharge valve configured to discharge the air stored in the plurality of air tubes to the outside; and 
 a portable pump to be mounted on the discharge valve, the portable pump configured to inject air into the plurality of air tubes, 
 wherein the portable pump comprises: 
 a contact portion configured to fit with the discharge valve; and 
 an elastic body connected to an upper side of the contact portion, the elastic body having a volume greater than a volume of the pump. 
 
     
     
       8. A wrist protector, comprising:
 an air tube configured to support a wrist joint of a user; 
 a pump including an air inlet communicating with an outside and an air transfer hole communicating with the air tube; 
 a check valve configured to allow an airflow from the pump to the air tube and block an airflow from the air tube to the pump; 
 a discharge valve configured to discharge air in the air tube to the outside; and 
 a protection plate formed of a more rigid material than the air tube and configured to enclose an outer circumferential surface of the air tube, 
 wherein the air tube comprises: 
 a first tube portion and a second tube portion partitioned on both sides by a thermobonded line formed at a center of the air tube; and 
 a connecting tube portion configured to enable the first tube portion and the second tube portion to communicate with each other, 
 wherein the air tube includes an air-noninjectable region positioned between the first tube portion and the second tube portion and enclosed by thermobonded line, 
 wherein the protection plate comprises: 
 a first branch plate and a second branch plate configured to branch in both directions from a central line of the protection plate; and 
 a vent positioned between the first branch plate and the second branch plate, the vent overlapping the air-noninjectable region. 
 
     
     
       9. The wrist protector of  claim 8 , wherein the discharge valve comprises:
 a discharge hose configured to allow an airflow between the air tube and the outside; and 
 a discharge bolt configured to open and close the discharge hose. 
 
     
     
       10. The wrist protector of  claim 9 , wherein the discharge bolt comprises a bolt flow path configured to allow the airflow between the air tube and the outside, and
 one end of the bolt flow path is blocked by an inner wall of the discharge hose in a closed state and opened toward the outside in an opened state. 
 
     
     
       11. The wrist protector of  claim 10 , wherein the discharge bolt is spirally connected to the inner wall of the discharge hose, and
 a discharge end of the bolt flow path is exposed to the outside when the discharge bolt is turned more than a predetermined angle with respect to the discharge hose.
